Foot, Hand & Mouth Disease - Nail Falling

Hi Mommies, my 2 had fhmd last month. It was not the full blown ones naman. Mild lang naging rashes nila. It started as sore throat then fever. When brought to pedia I was told it was Fhmd nga medyo late na nga daw because patapos na yun season as per pedia. My question is sino yun mga Mommies na nag ka fhmd mga kids then later on yun mga nails nagka bubbles then one by one natatanggal mga nails/toe nails. Ano ginamot sa mga nails or may gamot ba? Thanks
